Overview of Cisco ASR 900 Series Routers

Cisco ASR 900 Series RouterThe Cisco ASR 900 Series Router is a fully-featured routing platform designed for the cost-effective deliveryof converged mobile and business services. With full redundancy, shallow depth, low power consumptionand high service scale, this 3-rack-unit (3RU) router is optimized for small aggregation and remotepoint-of-presence (POP) applications. The Cisco ASR 900 Series Router provides a rich and scalable featureset of Legacy, Timing, Carrier Ethernet, Layer 2 VPN (L2VPN) and Layer 3 VPN (L3VPN) services in acompact package.

The Cisco ASR 900 Series Router is a fully modular platform with support for 6-Interface Modules (IMs),two Route Switch Processor (RSP) slots, two power supplies and redundant fans. Cisco offers a wide choiceof LAN and WAN interfaces available in speeds ranging from nxDS0 to 10 Gigabit Ethernet. The design ofthe Cisco ASR 900 Series Router delivers in-box hardware redundancy for all hardware components andsupports software redundancy with In Service Software Upgrade (ISSU) and Non-Stop Forwarding (NSF)support.

Release Notes for Cisco ASR 900 Series Routers, Cisco IOS XE Everest 16.5.11

Cisco ASR 902 RouterThe Cisco ASR 902 Router is a full-featured aggregation platform designed for cost-effective delivery ofconverged mobile and business services. With shallow depth, low power consumption, and an extendedtemperature range, this compact 2-rack unit (2RU) router provides high service scale and flexible hardwareconfiguration.

Cisco ASR 903 RouterThe Cisco ASR 903 Series Aggregation Services Router is a Cisco aggregation router product. This routeruses an innovative and powerful forwarding technology known as the Cisco Carrier Ethernet ASIC.

The Cisco ASR 903 Series Router is a 6-Interface Module (IM), 3-RU, hardware-redundant chassis with twoRoute Switch Processor (RSP) slots, and six IM slots. It supports fully redundant RSPs that allow for full RSPhardware redundancy, NSF, ISSU, and future RSP service upgrades. The Cisco ASR 903 Series Router runsthe Cisco IOS XE software and is supported since Cisco IOS XE Everest 16.5.1.

Cisco ASR 907 RouterThe Cisco ASR 907 Router seven-rack (7RU) unit router that belongs to the Cisco ASR90x family of routers.This router complements Cisco’s offerings for IP RAN solutions for the GSM, UMTS, LTE and CDMA.Given its form-factor, interface types and Gigabit Ethernet density the Cisco ASR 907 Router can also bepositioned as a Carrier Ethernet aggregation platform.

The Cisco ASR 907 Router is a cost optimized, fully redundant, centralized forwarding, extended temperature,and flexible pre-aggregation router.

C H A P T E R 2New Features

This chapter describes the new features supported on the Cisco IOS XE Everest 16.5.1.

• New Software Features in Cisco IOS XE Everest 16.5.1, on page 15

New Software Features in Cisco IOS XE Everest 16.5.1Following are the new software features:

• 10G SAT

Service activation testing (SAT) is designed to measure the ability of a Device Under Test (DUT) or anetwork under test to properly forward traffic in different states. 10 Gigabit (10G) SAT session is nowsupported on Cisco ASR 900 RSP2 and RSP3 modules. Any SAT session with a rate-step greater thanor equal to 1 Gbps is considered as 10G SAT session. For more information, see IP SLAs ConfigurationGuide, Cisco IOS XE Everest 16.5.1 (Cisco ASR 900).

• Additional Flex LSP feature support

Effective Cisco IOS XE Everest 16.5.1, the Cisco ASR 900 routers have enhanced the support for FlexLSP. Flex LSP also known as Associated Bidirectional Label Switched Paths (LSPs) are LSP instanceswhere the forward and the reverse direction paths are set up, monitored, protected independently, andassociated together during signaling. The RSVP Association aims to bind the forward and reverse LSPstogether to form either a co-routed or a non co-routed associated bidirectional traffic engineering (TE)tunnel.

In this release, Flex LSP supports the following features:

• SRLG Protection

• Non-revertive

• Sticky

• Hop count and cost max-limit

The G.8275.2 is a PTP profile for use in telecom networks where phase or time-of-day synchronizationis required. It differs from G.8275.1 in that it is not required that each device in the network participatesin the PTP protocol. Also, G.8275.2 uses PTP over IPv4 and IPv6 in unicast mode. For more information,see G.8275.2 Telecom Profile.

• Support of Adaptive Clock Recovery (ACR) on 8-port T1/E1 Interface Module

Adaptive Clock Recovery (ACR) is most commonly used for Circuit Emulation (CEM). ACR is anaveraging process that negates the effect of random packet delay variation and captures the average rateof transmission of the original bit stream. ACR recovers the original clock for a synchronous data streamfrom the actual payload of the data stream. In other words, a synchronous clock is derived from anasynchronous packet stream. ACR is a technique where the clock from the TDM domain is mappedthrough the packet domain.

Effective Cisco IOS XE Everest 16.5.1, ACR is supported on 8-port T1/E1 interface module. For moreinformation, see Configuring Pseudowire.

• Table Map MDT Index Optimization

Effective with Cisco IOS XE Everest Release 16.5.1, if the same table-mapping is applied on multipleinterfaces, the MDT index is shared across these interfaces. Thus increased scaling of table-map ispossible if table-mapping is reused. For more information see QoS: Classification Configuration Guideand Quality of Service Configuration Guidelines.

• TWAMP Responder with VRF support

The Cisco ASR 900 RSP2 and Cisco ASR 900 RSP3 modules now support IETF Two-Way ActiveMeasurement Protocol (TWAMP) responder on a Cisco device measures IP performance between theCisco device and a non-Cisco TWAMP control device on the network. For more information, see IPSLAs TWAMP Responder.

C H A P T E R 4Restrictions and Limitations

• The ip cef accounting command is not supported on the router.

• Crash may be observed on the router when:

• EoMPLS, CEM, ATM and IMA Pseudowire Redundancy (PW-redundancy) configurations existwhile switchover and fail-back of the pseudowires are being triggered, and the show platformhardware pp active pw eompls command is executed.

• Configuration sync does not happen on the Standby RSP when the active RSP has Cisco SoftwareLicensing configured, and the standby RSP has Smart Licensing configured on the router. If the activeRSP has Smart Licensing configured, the state of the standby RSP is undetermined. The state could bepending or authorized as the sync between the RSP modules is not performed.

• Evaluation mode feature licenses may not be available to use after disabling, and enabling the smartlicensing on the ASR 903 RSP2 module. A reload of the router is required.

• Ingress counters are not incremented for packets of the below format on the RSP3 module for the 10Gigabit Ethernet interfaces, 100 Gigabit Ethernet interfaces, and 40 Gigabit Ethernet interfaces:

Packet Format

MAC header---->Vlan header---->Length/Type

When these packets are received on the RSP3 module, the packets are not dropped, but the counters arenot incremented.

• ISSU is not supported between a Cisco IOS XE 3S Release and the Cisco IOS XE Everest 16.5.1.

• IPSec is not supported in Cisco IOS XE Everest 16.5.1.
